Reaction Steps

The title compound was obtained as the tri-hydrochloride salt by the method used in the preparation of 3-{2-[5-cyclohexyl-1-(3,3-dimethyl-2-oxo-butyl)-2-oxo-1,2-dihydro-3H-1,3,4-benzotriazepin-3-yl]-acetylamino}-benzoic acid methyl ester (Example 1) except that (3-amino-5-methylamino-phenyl)-methyl-carbamic acid tert-butyl ester (prepared in four steps from 3,5-difluoro-nitrobenzene) was used instead of 3-amino-benzoic acid methyl ester in step e, followed by reaction of the product obtained, in place of (3-{2-[5-cyclohexyl-1-(3,3-dimethyl-2-oxo-butyl)-2-oxo-1,2-dihydro-3H-1,3,4-benzotriazepin-3-yl]-acetylamino}-phenyl)-propyl-carbamic acid tert-butyl ester (Example 41, step a) according to the method of Example 41, step b. 1H NMR (DMSO-d6) 9.83 (1H, br s), 7.55-7.45 (2H, m), 7.26-7.14 (2H, m), 6.79 (2H, br s), 6.26 (1H, s), 4.77 (2H, s), 4.31-4.26 (1H, m), 3.96-3.91 (1H, m), 3.65 (4H, br s), 2.86 (1H, m), 2.72 (6H, m), 1.84-1.64 (6H, m), 1.34-1.10 (13H, m). Found: C, 55.92; H, 6.79; N, 12.84%; C30H40N6O3.3.0HCl requires: C, 56.11; H, 6.75; N, 13.09%.
